使用NetworkManager连接VPN一直失败，于是手动去连。出现ppp0了。可是接下来总是设置不好路由，无法上网。我把ifconfig的内容写下来，谁能帮我看一下呢：
eth1 Link encap:Ethernet HWaddr 00:0e:35:ab:d0:7b
inet addr:130.160.184.62 Bcast:130.160.187.255 Mask:255.255.252.0
ppp0 Link encap:Point-to-Point Protocol
inet addr:130.160.45.55 P-t-P:130.160.15.17 Mask:255.255.255.255
默认的route -n是
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
130.160.15.17 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
130.160.184.0 0.0.0.0 255.255.252.0 U 0 0 0 eth1
169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth1
0.0.0.0 130.160.184.1 0.0.0.0 UG 0 0 0 eth1

多谢了
